This board has been used
in different design 3D engrave machines, millers,
routers.

Include
manual control circuit to
test all 3 axis step motors manually

Step Current(r)
extension board (Optional:
See my other auctions): Step Current technology is
used to decrease the current upto 1/2, when motors are
in idle for all axis so as to
protect expensive step motor and driver board
for
long time running.

?? * See TB6560 Datasheet by
TOSHIBA. The full current is preset at 2.5A by resisters for this board (you can
adjust it by changing them).
